Embodiment Construction
[0031]Hereinafter, the embodiments of the present invention will be explained with reference to the accompanying drawings. However, the embodiment of the present invention can be changed into a various type, and it should be not understood that the scope of the present invention is limit to the following embodiments. The embodiments of the present invention are provided in order to explain the present invention to those skilled in the art.
[0032]In manufacturing the optical waveguide, a clad material is coated on the plane substrate, and the photo-sensitive polymer is coated thereon as the core layer. For laser direct writing process, the laser beam is focused and irradiated on the core layer material and the size of the beam is adjusted to a desired size. The stage of substrate is moved to write the pattern of the optical waveguide. Alternatively, the laser beam may be moved. The refractive index of the exposed pattern becomes larger than that of the material, which not exposed, the...
